| domBuilder( | |

| "Wouldn't this be cool?", | |

| // <html> | |
| // <head><title>Wouldn't this be cool?</title></head> | |
| // <body><div id="container">Hello, world</div></body> | |
| // </html> | |

| // Here we create a new child or traverse upwards if b[0] isn't defined: | |
| d = b[0] ? (c = m.createElement(b[0].source),d ? d.appendChild(c) : c) : d.parentNode || d, | |
